Combo Contents

This bundle pairs the ASUS TUF GAMING B850M-PLUS motherboard with the AMD Ryzen 9 9950X processor. The board uses the AM5 socket and supports Ryzen 9000, 8000 and 7000 series CPUs. It provides two DDR5 DIMM slots with a maximum capacity of 256GB and includes AEMP optimisation plus EXPO support. The CPU delivers 16 cores and 32 threads based on the Zen 5 architecture with a 5.7 GHz max boost clock.

Target Builder

Enthusiasts wanting a compact mATX platform with strong multi-threaded performance will appreciate the 16-core CPU and PCIe 5.0 x16 SafeSlot. The board also supplies dual M.2 slots (PCIe 5.0 x4 and PCIe 4.0 x4), Realtek 2.5Gb LAN, WiFi 6E and a USB 3.2 Gen2x2 Type-C port at 20Gbps. Builders needing four memory slots, a larger ATX form factor or an included cooler should consider other options.

Deciding Spec

The motherboard offers only two DDR5 slots capped at 256GB total, so memory expansion stops at two modules. If your workload demands four DIMMs or higher aggregate RAM, this board will not fit.

Questions about this item

Which DDR5 capacity and speed should I pick for this combo?

The board has two DDR5 slots supporting up to 256 GB total. AEMP and EXPO profiles are supported, and the Ryzen 9 9950X officially runs DDR5-5600.

What does the 5.7 GHz max boost mean for daily workloads?

The 16-core, 32-thread Zen 5 CPU can reach 5.7 GHz on lightly threaded tasks, while sustained all-core speeds will sit lower depending on cooling and power limits.

What does the USB 3.2 Gen 2x2 Type-C port at 20 Gbps actually deliver?

The rear 20 Gbps Type-C port provides the board's fastest external connection for compatible drives and peripherals.
